Question for the masses. Not sure if the question needs to be asked in a higher forum than this (i.e. the editor forum).
What should highways in Newfoundland be known as? Highways or Routes?
We’ve got routes:

Highways (and thanks Google for blurring out the TCH logo, good privacy concern there):

Or is it as simple as “Highway 1” for the TCH, and “Route xxx” for everything else?
